Default Stock Carter Interceptor GTR 250

So here it is...the mighty GTR. Ask the guys that own these things how they like them and they'll tell you they are the best thing since sliced bread. Carrying a claimed 20hp SYM 250cc engine, how will it perform on the track? It's kinda heavy if you ask me. Lets see if it is all hype or if it's the real deal.

SPOILER ALERT...if you want to see the results, drag your mouse across the next few lines to highlight them. Otherwise, just watch the vid.

Standing Start 34:88 - TRACK RECORD HOLDER!
Rolling Start: 33:04 - TRACK RECORD HOLDER!

The GTR now carries the fastest recorded times on our track and is the new standing start record holder, new rolling start record holder, and fastest time ever record holder. Ya...it's the real deal.

I need to do an actual measurement on it but you'd need all of the same obstacles to do a comparison. There are whoop-di-doos, one jump etc. The GTR would have got better times with better front suspension and bigger brakes but that's the point of doing these tests is to see how well it does as a unit. Those whoop-di-doos were hell on it. Front end literally in the air!

It's a totally stock 250.

Ya I have to admit that I am pretty impressed with it. I think I could have pushed it even a little harder at the end of the long straight and into turn 3. I only wish i had track attacked the Pilot when I had it. It clearly would have been the number to beat and the ultimate bench mark.

Eric, won't a 15 slow you down a tad?

no it should pick up about 3 mph. the bigger the top sprocket the more top end, carter did have a 17 tooth top sprocket that would make it run 62 mph. I can get 15,16,17 tooth ones.

another trick to get more speed is to remove the metal bushing in the main spring.

the bushing is a metal seat that the spring sets in, its easy to change but the axle sprocket is a pain

Is the trick with removing the bushing isolated to the 250 or would this also work on the gy6 150cc. Does this allow the pully halves to get closer together? Inquiring minds want to know. And last does removing the bushing create any potential for catastrphic failure ?
