Is there a easy tuning engine?
Hi guys,

You couldn't beleive how many trouble I got with the TT Redline!!! I just want to throw it away!

I am seriously thinking of swhitching to electric! I just want to maybe give a try with a new brand of engine. What is your experience with the NovaRossi? Easy to tune or not? Maybe the new OS55?

Thank you for your advices.

If you want to work with the redline pm me, and i'll try to help. I tuned about 6 of them now. they are different, but work well after you figure them out.

As for the new engines, I'll go out on a limb and recommend the OS 55 HZ. I havent even seen one for myself, but the 50 hyper tuned really easily, and was pretty consistent. I have an OS 91HZ,( and have tuned a few others) and it may quite possibly be the easiest tuning engine I have ever had. I have had waaaaay too many to truly remember, but the 91HZ is a Ron Popiel, "set it and forget it" deal. It runs extremely well while still gently rich, hence a wider range of "tuning". I say all that to say that if they can duplicate that with the new 55HZ it too will be a winner.

Which pipe are you running on the Redline?

man I still think that the hyper 50 is by far the easiest motor to learn how to tune hands down. I learned on that and easily progressed to tuning my 91hz. just my .02

Can't get much easier than the Hyper 50. Set the low half way through it's travel and unscrew the high needle 1 1/2 turns from full closed and tune from there. If high end power is lacking (which it probably will be at 1 1/2) just turn it in a few clicks at a time. If it is bogging too much in the low/midrange, very slightly turn the low needle towards lean (this needle only has 180 degrees of total travel from all the way lean to full rich).

Most of my Hyper 50s ended up around 1 turn out for the high and just slightly lean from the mid point for the low needle.

I've owned almost all of them and the OS was the easiest for me to learn to tune properly. The YS was not easy either, I found the needle adjustments where much more dramatic. Compared of OS one click made a huge difference.
