Lorenzo,
Bikenuno has one in, I still got mine in. It fits ok. Some fins on the cooling head foul the aluminum tank and side plate, might be ok with the plastic tank, but it's just a question of filing them down a bit.
This engine will either bring a smile to your face, or tears, depending on how you run it. If you've seen the 2 onboard video clips on my nitrobike site, you'll know what I mean. And that was with the throttle limited to between 40 - 48%. The track was damp and slippy on the rearview clip, which is why the wheelie at the end trashed the bike. I wasn't ready for it.
I'm sure Bikenuno had similar problems.

Hi Lorenzo
I have the NR 15, but is the non pull start version, because I have it in a Rg1. Now I bought a cheap OS 18 to evaluate the diference. I assume that you have a NF. The OS has a huge head that surely has to be cut to install in the NF, and the carb main needle is angled wich poses more instalation difficulties. The NR should be easier to install, but be carefull because this one is very powerfull Be carefull with whellies because those can break your bike. I managed to make some but with entusiasm, in the end I got a triple jump and a bent front fork. The one you need shoul have pull start but neverthelees the power is tremendous. I use 100% throtle with a rich setting and 80% exp. to be able to drive it in the corners.My local race track has a huge straight. If you do not have a huge one cut down the throtle or be sure to have the nicest brakes.

What is "showhorning"...? I am about to invest into a OS18 and what exactly did you have to do to get it to fit...also I am throwing mine in a NF.

Well, currently I do have two NF's and the Bergonzoni, which I'm still trying to get my starter box working. One of the NF's has the Novarossi .12 and the other has the Siro .12, but I need more power then the .12 can provide since I would like to try stunting with the bike by wheelie's and the .12 just cannot put the front tire off the ground.

I was just looking for a more powerful engine that will fit without too much extreme modifications? I thought the LS .15 would fit without doing too much? But, boys like power so that is the goal.

I'm dialing in my second NF and my first one rocks and runs great! Almost 2 1/2 gallons has been run through the engine. I need to get the bergonzoni going though.

Lorenzo, did you have much trouble with the Sirio engine? I just got my NF together completely kit, including the engine that came with it. Any tweaks you can pass on to get it running when the time comes?

TIA

I changed the plug to an OS A3 and didn't change any settings. It fired right up and I just let it run rich until I could run several tanks of gas though it. It might bog down just a tad, but just give it a little gas until it warms up and then just let it run about until the engine can brake in a bit.

About the only thing that I found out about priming the engine is to pinch the rear tube that comes out the bottom and blow into the exhaust pipe, which will force fuel into the carb. This is about the only way you can prime it.

I prime my nitro engines by putting my finger/thumb over the exhaust tip and pulling the starter a couple of times... I don't have a nitro bike yet (40+ cars, 5 nitro)but I'm sure using your finger vs. putting the exhaust in your mouth would taste better and be healthier...LOL

that is... if you can (I'm not familiar with the nitro bike's layout)

Hi there
I have already posted somewhere else that I have a OS 18 in a RG1 waiting for run in. The Os 18 will need some mods to install in the NF. This engine has a huge head and has to betrimmed to be able to fit in the bike without interfirinfg with the gas tank. Also the main needle is angled but I think in the NF there is no trouble with that. In the RG1 I had to trim also the side plates, but no major trouble.
