Hi Rod, I would be interested in the 250L pipe specs also if you dont mind letting us have them. I have built some L pipes for someone that were for the seel barrels, but unfortunately when he also tried them with standard L barrels although they gave good peak power they had a big hole in the mid range power . Would be interested in comparing the specs of the two different pipes to maybe get an idea as to why the seel ones gave such poor mid range power. It would be interesting in how different the porting was on the seel barrels by comparison to the standard L barrels but unfortunately it wasnt my bike so I never got to see them. Hence the only info I have is the seel pipe spec , but would be intersted in the L pipe spec for comparison.
Cheers Rob

Yes ok on the exactweld pipes. A friend of mine has a set of L pipes that I think were made by exactweld. I am pretty sure he had someone copy them for him a few years back but unfortunately the copies didnt work as well as the origionals. I will have to try and remember to ask him about them when I next see him. Pretty sure the exactweld pipes were blown pipes.
Hope I am right here, but I think "tassie tz " is Grant. If I am correct you came over and rode a kr350 in some icgp rounds in 2011. Hope I am thinking of the right person but please excuse me if I have got my wires crossed so to speak.
Cheers Rob

Cheers Grant. Thought I had it right and it was you but wasnt sure. Glad you thought the icgp racing was good, despite using up all the bad luck. Wonder how you found the kr350 by comparison to a tz. I remember back in the day it was said they were no quicker than the tz,s on top speed but better mid range so hence better off the corners. About what you would expect from a disc valve motor in comparison to the piston port tz. Wonder if you got the same impression of the kr. Hope your injury heals reasonably quickly Grant and if you want to you get back out racing again.
Unfortunately I had a very serious injury myself at the start of the 2010 season, and did intend racing at the snetterton icgp round in 2011 as a first outing back out on a bike. 3 laps in to the first practise session I promptly slung the bike down the road again. Certainly didnt need that crash I can tell you, but with luck come march I will be back for another go. I just keep getting older but no damn wiser LOL. Bloody adictive these tz,s. Raced my first one back in the 70,s and still looking forward to getting back out on one again.

Yep ,you hit the nail on the head about the KRs performance ,alot like the rotax ,more torque than the TZ , It was hard for me to adapt to the KR after only ever racing TZs ,lack of track time and trying to learn the tracksslow learner But the challenge and rare oppotunity to ride Jean-Paul KR in the ICGP was an experience that I will treasure,so if my mind ,body and wallet are good I want to do more .Back to the L pipes , if you discover anymore let us know please
