I think the Worlds S7 was purchased in the 90s. I need to check to make sure it's not rusted. . I kept it in a cool place with oil in the engine.

I have the tooling to make the Nova .21 Rod fit the slightly larger crank pin on the .21 RB's

Hi guys- need some help- I have a RB BXr sls DI5 and i need a rear engine bearing- I can't see to locate any info on Size- it's Not a 14.5x26x6- they don't have the step down like this does- Thanks in advance

Ball Bearings for Nitro R/C Engines - NOVAROSSI WORLD

You probably need the 16009
The SLS is the super long stroke and in that time they did come with special bearings.

If you are handy or know someone who is, you can modify the crankcase to fit normal bearings

Rb yuukanai 1 engine tune?
 

Can someone please help bought this awesome engine but not to sure on tuning an no idea where it's at...... where would be a good starting point please if I was to turn it all back to closed. Thank you

Just as an update to previous questions on here and to clear something I have been asked a few times, the old RB 01122-C Con rod has now been superseded by the Novarossi 07014 Rod for anyone wanting to rebuild their old motors. This has been mentioned above but i dont think anyone ever gave the part number.

Afternoon all, hope your all well.

I'm new to this this forum, ive just finsidhed rebuilding my X1CRT pro which has the RB WS7 2 X3 engine. Its been a long time since it last run....maybe 8 years and im wondering whats glow plug to buy and the RB ones are impossible to purchase in the UK. Also unsure whether i need a standard or turbo plug??

Any guidance would be much appreciated

nova 6 probably

The WS7 was a Novarossi based engine. Stock, they came with "standard" head, but a turbo head was an option. RB went out of business a while ago, so finding parts isn't easy... However, as far as plugs go, no need, as most standard plugs will fit. Like previously stated, a Novarossi standard "6" plug should be perfect, in colder weather (under 55* F) you might try a "5". There can be allot of other things that will effect your engine, but if you use a "6", it pretty much works all the time...
