Re: My Suzi T500 Project (Finished Video & Pics!)
First of all thanks as always for all the comments and suggestions, really appreciate it
To address the porting work first: Eric from sundial motorsports is well respected for his work tuning T500's, he has many years of doing this under his belt. My requirement from Eric was that I would end up at around 55hp with all of the engine mods, I told him I wasn't too bothered about the bottom end but he insisted that he port it so that it would have good power all through the rev range. This was corroborated by a member on here that did the calculations for my pipes, he told me that the porting specs on my cylinders is not real crazy. The pipes were also not designed for power all in the high rpm range, they should work well at low rpm as well as up higher.
I raced two strokes for many years and I know the basics about how they run and how one thing will effect another but unfortunately I never really paid much attention to the carburation, I had a tuner that worked with me on that. I guess what I am saying is that I can tell by feel that this is most likely not a porting issue but a jetting issue.
Anyway I will do a plug chop at full throttle to check where I'm at on the main jet. My carbs are brand new and I have had them totally apart and there are no obvious issues. All the jets I've used have been genuine Mikunis.
Again keep the comments coming I am glad there are people interested in this it is a big help!
