Rup,
Did you have to remove or relocate anything to get that Pipe on??? weighing my options as far as pipes. We won't be doing any racing so we are looking at all the pipes.

ya had to move stuff . the oil injection is now gone no biggie. we just mix now ,but the air box on the DRR is the furthest back under the oil tank. well it had to come out too, so i made a custom airbox to fit between the frame and pipe. then i talked to hetricks again. he told me the stock airbox would bolt right to the side of the motor below the carb and you could use the stock airbox.. the rest fit good.. and it sounds good too a little loud , but i like it

When you change altitude that much you will need to rejet. Gain in altitude, go down in jet size. Lose altitude go up in jet size.
