Another +3 Stroker Crank Thread...

[acezeesawtooth]

ok so im starting to learn alot thanks to blasterforum.com I:I but not enough yet. so i just purchased a 240 bb by vitos and it was ported and milled by wildcard im planning to tear my entire blaster down and redo it so i want a +3mm stroker crank in there too. my question is since the head is milled to run on 93 octane do i need anything else once i get the new crank? do i need that spacer it comes with? and what fuel might i need to run on after?

you should probably talk to wildcard because the stroker crank will require different port timing.

yup, it sure will but it will be a worthwhile cost I:I

i know that it will need to have more port modifications but i guess my real question is am i gonna have clearance issues?

The head will need to be milled for the +3 crank. Or you have to use a spacer.

wildcard should tell you everything you need to know when you contact them. sounds like some great mods man

so i talked to wildcard and since the cylinder was ported for stock stroke it cannot be ported for a +3 stroke without resleeving... so im just going to stick with my stock stroke i will have plenty of power without it so thats that

if you go with a 115 mm rod, you should have plenty of room to adjust the porting if it isnt an overly hogged out wannabe drag cylinder. you would then need a spacer to make up for all or part of the extra rod length.. cometic can make various sized spacers so yu are set there.

so phragle you think i should talk to another tech about this... its just an aggressive trail port nothing to vicious

 

[phragle]

just do the math... all you should need is a degree wheel and some calipers.

ok phragle im sorry to do this to you but im new to four wheeler engines 2 strokes especially so i dont know what math to do
