sleeve question

[89blaster89]

im thinkin about getting aggressive trail porting eventually but my cylinder is at 68mm so i only have one life left then it will need re-sleeve, my question is if i get my engine ported and then resleeve it does that mean i will have to send it back in to get the sleeve to match the porting?

Depends on where you get it sleeved at. A regular builder might not charge full price to just match sleeve to existing ports. I would start looking for a new cyl with more lives left in it, and just do a DIY port on your existing. Might not get quite as much as a "real" port job, but it will still be a good increase. Just don't raise the ex much or you will end up with a drag cyl. "MUCH" is only a MM or so.

FYI, getting a sleeve installed is pretty pricey.

i would like to do that but i just dont have the money for that, ive been on the same wiseco topend 68mm for 7 years and it has 135psi compression still so it should last awhile longer

i was too when i started to do mine but its easier to take materal out than put new in

 

[89blaster89]

id rather just send it to a pro but just in case what tools would i need to do it my self?

 

[mud runner]

i used a dremmel and alot of diffrent grinding stones and some320 or 400 grit sand paper and some safty glases and another tip of advice its better to do a lil and do a lil good than do alot and do alot of dammage

DiY is not really all that difficult, take it slow, watch what you doing and be patient!

im doing the DIY porting right now and it really isnt that bad. just be careful.

 

[89blaster89]

well im getting the head machined for stock porting and stock stroke right now. so what would i have to do to my porting to match the head?

 

[mud runner]

i dont think anything

 

[blaster82]

nothing to match the head. porting is all in the cylinder. (mainly)
