Just weighed each end today 158lb rear and 161lb front so it adds up to 319lb not sure how accurate that is! I was sure it was lighter than that, my KTM is 228lb and it doesn't feel a lot different ot the Suzuki. Must be the weight is higher up on the KTM
Check to make sure your coils and motor are grounded well to the iggy.I had a suspect ground to my coils and the bike would idle fine putt around ok but as soon as the pipe started building pressure, it would fizzle out.
Finally picked up my pilot jets this week Tried the 45's first and it still ran about the same, idle was high though when I started it. So I put the 25's in and I had to turn the idle up when it started, it ran quite a bit better (with air srew 1.5 turns out). So next I played with the air screw but it is still very difficult to detect any change in the way the engine is running, it didn't stall or rev up no matter which way I turned the screws. So I set them at half a turn out and rode it and this made it run worse. Then I set them at 2.5 turns out and that made it run better than any other setting so far. It is still not wanting to pull cleanly when you first pull away then suddenly it takes off. What should I do next to clean it up even more?
John I wanted to give you props on the pipes. As I found out gas welding 22ga. is very tough!
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!
