The cylinder can be ported and Nikasil'ed. Nikasil is just a coating on the cylinder wall. I would say a Sparks TT, ESR TRX-5 would be pretty good pipes with that set up, although others may chime in with their findings.I picked up an 88r motor that CT racing built to an 330 stroker running an 100 octain. I was told that it isn't ported but has an Nikasil cylinder. About 20 hour on it. So witch pipe and silence do you all think I should go with? Is 20 hours alot af time?
If that CT cylinders not been ported, then the ports are as they come stock which would make for a bottom end engine.
The ESR TRX6 or the CT midrange MX pipe would work well with that type of porting.
yea mine has about 10 hrs on it and i was cosidering re ringing it for the 2008 racing season but im not sure if i should try the if it aint broke dont fix it mentallity and leave well enough aloneYes. The cylinder isn't ported. The guy I bought it from made sure I new this. I guess I'll go with an CT midrange since I have there silincer.
Another question. If I put new rings in it do I have to hone the cylinder or can I just slap it in? Can I do an compression test with the motor out of the bike? Would the reading be correct?
