also would a single 42-45mm side drauft webber be better the twin 40-42's?

definately not single sidedraught= 1 ventury per 2 cylinders twin sidedraughts=1 ventury per cylinder so even if you had a big single it would have to be double the size to produce the same figures as twins but would not respond very well at all

rito thanks

i reckon to get the best performance out of your A15 carbie wise i would go twin webers but then to top the webers would be quad motorbike carbs but thats a fairly fiddly setup to get goin nicely but are pretty darn mean

so has anyone got a good idea of a budget i should have for a full build from jts?

Without wanting to be a smart arse I offered you a fully built motor for $2300 and you couldnt afford that much, to rebuild one to the same specs would cost double that.

no i said ill sell my buggy and see...i also said money isnt a issue...ill pay anything as long as it has atleast a realiable 150hp...ive gota buggy forsale for 7800 and that seems as if it will be going soon..so with 7800 i think ill afford a decent motor dont u?...also got perants

Why not buy Sidedrafts already built A15 for $2300 to build a simaller engine would be costing way over $4k. Then you have to buy a set of carbs dizzy extractors ect ect its going to be quite expensive. Even if you where to spend say $2500 on a basic A15 build it wouldnt get you that much.
Out of interest I had twin 45mm webbers on my A14 they where fine you just need to jet and use correct size chokes ect.

because mine motor is pretty much brand new so wots the point? i have everything done to mine except a decent bore,cam and 40mm webbs...so i think its more logical to do mine...

btw he sold the motor the same day i asked bout it
