I wouldn't want a modded one. Its fast enough LOL

Well it'd be going into an on-road car, so the more power the better. No such thing as too much! It has been a toss up for me between the Roma and the 28-7T.

Thanks Chris. I'll try leaning the LSN and see how it responds. Its very close to being perfect, just trying to get that last little bit of performance out of it can take some fine fine tuning that I often don't have the patience for. LOL

Having trouble keeping the BTT models straight...do I have this right?

BTT = Ceramic rear/steel front bearing
BTTA = Steel bearings front and rear
BTTS = Ceramic bearings front and rear

Are there other differences between these engines?

Thanks!

You are correct.

Thanks! Any other differences in the engines? Carb/crank/timing/etc?

the front bearing was leaking.. shut off as soon as i hit it with the motor spray

All the same besides the bearing differences you noted.

Keep a eye on the HSN as well. Write down where your needles are now for a reference point to go back to. Make small adjustments.

i was trying not to make too much light of this but many of the nova engines as of late have been coming with a subpar front bearing (compared to 17011 ;)) and have been causing some issues , the more of you guys that show your concern to serpent usa/desoto racing the quicker the issue will be remedied or email novarossi direct through their website

hope this helps


i try to tell my customers of this and let them choose which way to go on the front bearing



happy motorin',
Monty

or call me , dork :weird::lol:

thats the bearing i ordered. no more front ceramic for me..

will do Knuckle head. Just been crazy busy. i'll call you later tonight.

theres no prob with front ceramic balls , theres problems with designs of some aftermarket and factory front bearings


i am super spoiled by the 17011 front bearing ;):nod:

My engine running much better now with the double sealed bearing.Thanks again Monty..

I always called you Dork, but you didnt seem to like it too much :D
