New Builds - Learners

I will try and put up a picture of our naked bantam for you JB later from our static display, i mean attempt at racing at Cadwell



Eddie

Great! Thanks Eddie. I am working on some fantastic diagrams I´d like to to put in Phenomena Plus -- `Power Thro´The Gears´ -- by Trevor... if I get them finished before falling-over that is !!

Cheers!

Wünderbar Edward! A mean machine that distinctly looks like a Racing Bantam.

Cheers!

Cheer JB,

It is meant to run with a fairing but we ran out of time to fit it so cobbled some plates and brackets up on friday morning.


Robbie, when you have time would it be possible to explain again about getting some better/bigger engine plates made up and raising the engine, getting things in line.


Kind Regards


Eddie

Good Evening all,

Well sanity hasn't taken over and we have sent off for snetterton.


Now to try and remove as many gremlins as possible we would like ideas and suggestions, we have a standard clutch and are running a amal mk2 34mm.

Do we change these or adapt what we have?


Kind Regards

Eddie & Malcolm

Standard clutch should be alright running surflex plates...
Bit worried about your carb .... should that read 'Amal' ?
or do you not rate that make of carb ?? lol

Thanks for that mike,

Sorry for the mistake!

Eddie

the plug looks a safe colour, but its hot enough to burn oil away on shiny face, or its just not run under load for long enough ? I'm not sure what Alans opinion is on the carb.

you can't do comments on the running, as there is simply no build up or carbon on the piston crown to be able to say with any accuracy, but what you can say is.
its very oily and it looks a tad rich, but not with any accuracy.

you have a pilot system or cab issue, I agree something going on, just will not start when cold or very difficult, but what you can say is it oils up as soon as you run it slowly or after ticking over.

my opinion is you just had a lot of bad luck, a bit more practice starting getting underway and if Im really honest I think you did bloody great getting to where you are with the resources and knowledge you guys have
also the bike just looks the tagems, but wait till it gets going you will surprise your self, but not before others have noted its turn of speed.!!!!!!!?

too much oil perhaps ? is the only real comment I could be able to make, others may have other ideas or opinions, I hope.

Ed.s asking for help here, so come on what do you guys think ? I see Mike has chipped in thanks Mike this is what new starter need lots of opinions to lots of answers or questions!

regards Derek

Cheers for the comments Derek,


All a big learning curve for us, Dad just wants to get a lap done atleast!

Plenty for us to work on, clutch seems very heavy although you can probably comment on that Derek. Need to sort proper support for the tank as it vibrates like hell, which in turn has worn out the sleeving on the coil fly leads so a bit to do.

Still a boost even if we didnt get out on track properly as we are moving in the right direction.


Kind Regards


Eddie & Malcolm

hello ed, looking good despite problems, it can only get better , just wondered what plug your using and sticky number size for the number boards, are they 6 inch?
thanks dan

Hi Dan I would say a 10 plug would be a good starting point safe too as for numbers check the ACU handbook it has the sizes in there or I could cut u out some templates if I had what number you are. will be at the crmc meeting lydden at the weekend on the bantam

hi rob what class you in Im in london this weekend may pop down is it sat and sun ?

Rob a few questions On the chain, Primary, what milage do you run your chains on before changing, Iwould imagine it depends on itmes like power revs if a 125/175 or how brutal you are with the clutch and size nine boot? now who said that"

the one I have on my bike seems to have streched quite a bit, this is the same item I used last year, but only did three meetings and as the bike seized not a lot of racing, I had three sezures with it now, sos should this be a catalist to change it, its looks ok, the joints apprear absolutly

when do you change them when you seize or do you milage them or number of meetings.

thanks Derek

Good Evening Trevor,

I have sent a few pm's regarding questions but I don't think they are going out.


Kind Regards



Eddie

Hi Derek
I am in the 200 two stroke class
chains. have been running these chain for sometime now dont think anyone has had one break which is good not like in the old days
mike powell had some rollers come off but that was on the black type chains I fill the silver ones are better

I tell the lads two for the season will do. in the past I have the same chain all season

Hi Eddie

it seems PM's dont move from your Outbox to the Sentbox until the recipient opens the message - implying that Trevor has not seen them yet.

He's not been on the forum recently so hope he is well.


Your bike looks great. Hope you sort out the gremlins real soon and have a good day at Snetterton.

Mick

thanks Rob

mick have you heared of AMALS and Mikunis suffering fron a problem with lever type chokes, the plunger of rubber issue.

seems I spoke to some one today and he says its a well known fact you can have issues with the choke not working correctly that appears to make it seem like the pilot screw is ultra sensitive. ?

O and Trevor was on today just after Nine this morning "I have ESP".

regards Derek

Hi Mick,

Thanks for the comments, hopefully we will have it running a bit better by then.


Kind Regards

Eddie

Hi Derek

There was an issue with choke rubber seals which I believe started a few of years ago when they started putting alcohol in pump fuel.

The rubber would swell and the choke would not seat properly - maybe thats what you are thinking of?

Mick

thank you Rob,

thanks Mick to add did this rubber thing, produce perculiarities with rich and lean jetting when running / starting as on mine the pilot is so sensitive, got to be somthing wrong just one blade of a screw driver turn and its so rich but all the way through the range, this is clearly having a pronounced effect in the mixing tube, that is affecting carburation on start part and full throttle openings. ?? this is really puzzling me, anyone know what Im refering to,

I had believed it was a damaged pilot screw seat, but had a probe down it it looks ok but it does have a flat btm and the screw is also the same looking rather burnished on the end, so it looks like its touching on the btm to close off the air, and only partly on the taper one side,

also it looks like the thread on this pilot screw is quite course and it has a bronze or Brass insert in the pilot screw hole, could anyone say this is original has it been modified ? before I got it, it was surposed to be new, or is this std Mikini Practice, it seems to have been done beautifully though.

regards Derek

Good Morning All,

We think we may have a leaking tank to add to our problems due to using petrol as we can't get avgas.

Is there anything we can use to seal it properly?

Regards

Eddie

`...may have...´ a leak Edward? sounds more like a seep if its not dripping....

... fibreglass tank I guess? The seep could grow into a proper leak during a practice or race and then Malcolm could be in deep trouble if his boots or leathers got soaked in the stuff!!

Someone on here might have a solution for instant repair ....

But that is a horror story, Eddie, because Petrol-oil mix means oil in the fibres where it is shredded. You need something like an alcohol type solvent or boiling water soaking for a long period -- [an old tin bath on top of the hot plate on the oven ...!?] -- to be able to get all of the oil out and enable the new fibreglass resin to take hold onto the old fibres.

I did it once with my fibreglass tank which had a split about 3 inches long in it. I bought Propanol-2, an alcohol solvent at our local chemist´s and repeated soakings had it free of oil -- enough to allow the new resin to set properly... Sorry! this doesn´t sound too helpful or hopeful....


Cheers!

Cheers for that John,

Dad is currently putting the bike back together and building his rollers so we will see how bad it is, I had the same problem on one of the others where someone had done a bad repair.


Kind Regards

Eddie

Evening All,

Any idea's for gearing for Snetterton as dad intends to try and do a lap this time!


Kind Regards



Eddie
