the 99's can be very difficult to tune and keep tuned

the 100's are easy to tune and yield excellent power with exceptional idling capabilities .

the odo77 plug is also a very friendly well performing plug .

your engine isn't here yet but shipped out today to my place

monty

Cool, I will toss(ebay) my extra 99's and get some 100's.
And take your time on my engine, no hurry!

Hi Monty,

Do you know if a 367 P/sleeve & R7 Rod would fit in a 21-5kt block

I blew the rod & shattered the piston in the 21-5kt but i have a spare 367 set.

Thanks kev

It will fit but the ports will not line up anywhere close.

If you need a 21-5k p/s set or p/s/r set pm me

Monty, i raced the JP 8 port for the 1st time today. Had a blast figuring out a new to me engine. It had really good snap out of the corners and 2/3 down the long straight. It needed a different pipe though. All i had was a 2045 RB and i put a short OS manifold on it. I will say that i was the only one that ran the 10 min. truggy race that didn't pit for fuel. Ed Bridges was there today and the 8 ports are his favorite nova engine. He thought it ran really well. I'm just used to my modded speed motors getting wild where the JP fell off a little, but the JP does have more bottom. I'm thinking abt trying either the 9901SS/41021 or the 9886/41021. What's your opinion please? Thanks, Rob Hamm.

I would recommend the 9886/41021 or dynamite 086hs.

Hey Montey, I have a few questions about the 21-4 and the 21-4c. Iknow they are pretty much the same mills except the rear ceramic bearing and some minor extra crank work on the 21-4c over the 21-4 tuned. Is there any other differences and have you heard anything bad about the 21-4c? I also didn't know if you sold them or were just on the service side of things.
Thanks again Bob

i do both Bob , sales and service along with tech. support

just let me know what you may need and i will do my best to get you hapy with the novarossi engine line.


i haven't had any issues with the plus 4's myself and dont foresee any issues with the plus4C's . differences are .5mm larger opening in crank throat and a killer ceramic bearing

same killer engine with a few upgrades

Monty,

I currently have a FMS for my truggy and just picked up a used P5 "hot mod" with very good compression for my buggy. I took it apart and think it could be due for a front bearing so I am probably going to do ceramics all the way around. What size rear bearing goes in this thing. Also on another note it has a standard plug and I was wondering if there would be any benefit (noticeable) to switching to the turbo button?

7x19x6mm front and 14x25.8x6mm rear http://www.novarossiusa.com/product_...roducts_id=288 this is the front one you want if you can get them anywhere

okay great! friday would be fine Monty. Can you send the request to [email protected]!! Thanks!

oh and thanks for the needle adjustments. someone told me the HSN was 3.5. good thing i asked you.

oh yeah before i forget, what is the correct shim for byrons 25% on the plus4. i believe i have one silver,copper, then silver. Sound about right?

4.5 is factory on hsn but 3.5 is about where you end up on race tune
