You said you had boyer ignition ?  Sounds like a standard set up to me. Black things a rectifier, blue a condenser.

Thank for that!! So just normal unleaded then? As I was told it should be old leaded Petrol but I can't get it anywhere.

Thanks

For the purposes of getting it started any petrol will do, for longer term running and piece of mind castrol do an octane boost / lead replacement .

[Climber Flywheel puller]

Im looking to buy a flywheel puller for a 1990 climber Ive just bought. I cant find a specific one on ebay but a bosch rotax one  is available. It is a internal thread of 35mm x 1.5. Any ideas if this is the right one. Thanks

Unless there is more than one fly wheel. M35 x 1.5 right is correct.

Anybody explain how the cold water trick works? 

Steam clean.

[Smokey Fantic 240]

You sure you need seals ? Does it run very weak / erratic, dry side seal. Burns gear oil which generally looks different to 2stroke smoke ? Other side.

Not just the exhaust needing a good clean out ?

 Perhaps I should put the blame on my TXR engine and its primary gearing, not myself....?

 

TXR engine is good, its the climber primary that's higher.

However, regarding primary gearing, that must be a matter of personal taste from b40rt, as the higher gearing works perfect for me. If not, why go to all the trouble changing clutch basket and so on when you could go for a 56-60t rear sprocket (if you really need to go that slow....)?? ?

Hi G, here we have to agree to differ. I ride in second gear in many sections and agree its very usable, but I do like the option of a lower first gear. 

( Are you going to Telford this year ? )  

[1982 SWM 320TL NEW]

I have an air cooled climber motor, but found the gearing very high, even with 10t gear box sprocket, and 54 tooth rear. Eventually I will change the crankshaft pinion and clutch basket for earlier ones.  Have fun !

2 day trial at D'All is very good I'm told, are you riding this year.

Welcome, you havn't kept the climber clutch casing ?

I was going to suggest j b  weld, trouble is if its not successful if make welding more difficult.

Hi b40rt thanks for the reply. I’m in Fife (Scotland) my only concern was the available space to fit a weld repair and the chance of shattering what is there with heat stress. 

@breagh Alan can you recommend anyone ?  I'm sure the plate would be ok being welded. 

 

[Sherco 50cc Stator problems]

A competent welder should be able to repair that easily, there's no real stress on it so doesn't have to be super strong. Possible cause being the stator was loose for some time. Where are you so people can recommend a welder.

I thought I read somewhere they modified the clutch to reduce engine braking ?

Did they give you legitimate reasons for runner those ratios? Most don't! 

Apparently these ratios are only ok if you mix fuel in 6L containers ?

Not sure I understand your question.  The key size is based on the diameter. The tightening torque is a function of several parameters (e.g., grade, diameter, pitch) but length really does not enter into it.  Are you looking for a specific bolt?

 

Yes, m8 for bottom shock mounts on twin shocks. No real stress on these, button tops don't tend to get snagged on passing scenery ?

[Budget Trials Build]

Excellent work, (thought you had been abducted !) exhaust as shown might lack bottom end power ?

My mistake, I'll blame my poor English skills.

In the US, McMaster-Carr  https://www.mcmaster.com/standard-rounded-head-screws has been a great reference source for as long as I can remember.

They say "fully threaded" or "partially threaded" (which is far less common).

Appreciate your input, I've yet to find any "partial threaded" I'm assuming its because the relatively small allen key size isn't sufficient for proportionate torque ?

FWB Products @ Stoke on Trent https://www.fwb.co.uk/ or Barfast http://home.btconnect.com/barfast/ these people also stock metric fine, I highly recommend Britannia Fasteners Burslem though they do not have a website.

Thanks triailrfun, I'll try both.

They're very common in the US, often called "button-head cap screw" or "socket button head".

Thanks konrad, common here to if you want set screws, but not as bolts.

Minor hijack, any one found a source for Allan button top bolts ?
