I have a small problem that I’m hoping somebody can help me with. I have a PX200EFL with a 210 malossi kit and supposedly a t5 4th standard 24mm card and sip R/H pipe the scooter has been dyno’ed and was 19.3 BHP and was rejetted correctly at the same time so I don’t think it’s a carb issue but I could be wrong. My problem is top end speed or the lack of it in my case. You see I can only get 65 MPH which is a bit of a pisser really considering and I was hoping somebody out there could help me get a better cruising speed maybe 70/75. Acceleration is not an issue as I do a lot of two up riding and I’m not really concerned about it but I’m sure I should be getting better speeds than 65 when 2 up. The main problem is 4th gear I can get 60 in third 2 up with out a problem but as soon as you put it into top gear it struggles and does not seem to want to go any faster. Even though I was told when I bought the scooter it had a t5 4th in it could it be that it’s not a t5 4th and this is why I,m struggling so much? Also I know it has a kit on but I don’t think it has been matched could this cause the lack of top end. Another thing is the rattling I get when I am at this speed could this be the small end bearings. A lot of questions I know but please somebody help me before I pull the last of my hair out.
