Haven't checked the clearance yet! The wheels are being blasted and re painted. I'm having this sent in for powder coating next week.

I'm not sure of the size of the rear sprocket? How would I measure it? By teeth? Or diameter ?
I fairly certain its stock?

to be honest, I've never riden a motorcycle.. Or even worked on one.. This is just a project I was interested in trying! I will possibly sell it after I've finished it. All the painting is being done professionally free of charge pretty happy with it

Fingers crossed it clears alright!

I am just after the number of teeth, my wheel originally came with a 38t sprocket but when I ordered a new set of sprockets and chain it came with a 44t rear sprocket which I suspect is stock but wanted to be sure.

Only one way to learn! That's a great contact to have! I'm trying to find somewhere to spray my tank that won't cost a fortune. Would rather spray it myself but don't want to go spraying 2k clear in my apartment complex ;)

44t rear sprocket on mine UK RSA model.  No reference in my manual?

Is that the standard battery?  As yours is the RSA kick start only model you could opt for a much smaller unit.  I'm considering a 1.2ah unit myself, it's about the size of a small chocolate bar,cheap too. 58 x 43 x 97mm 600grams. £10GBP

This is in the UK http://www.screwfix.com/p/sealed-lead-acid-battery-12v-1-2ah-58-x-43-x-97mm/63554

might need a resistor to reduce overcharging.  It's used in burgular alarms etc.

Thanks Gumper, no reference in my manual either. Pretty confident 44t must be stock.

I've just bagged a proper workshop manual from fleabay,  when it arrives I'll look to see if it confirms this, although I'm pretty sure 44t is standard.

Changing the subject somewhat.  Do any of you fellow RS owners have their front end in bits.  I'm looking into the possibility of a front end swap (due to the price of re-chroming or new stanchions) and would like some dimensions. i.e. Standard fork length, stem diameter off set and weight.  I could measure mine but I've got the backend stripped.
