[Jeremy 748R]

Hi Guys,

I'm going to be selling the engine from my 2002 748R and have a couple of questions. Will the engine fit any 748/9** frame? I will most likely sell the engine, airbox, injection, throttle bodies, wiring loom, ECU and termignoni carbon exhaust as one lot. Basically everything to fit it to any frame, but will it fit?

Secondly, any idea what it's worth. Will most likely end up on ebay, if none of you guys want it.

Will be putting a post in 'Market Place' once I know what frames it will fit into.

Thanks in advance

Jeremy

Hi Jeremy,

The 748R engine itself should fit in any frame. The only stumbling block is that the airbox will only fit a 748R frame. The "X" section of the frame under the airbox is completely different on the 748R to clear the huge airbox. Only the 748R has the throttle bodies inside the airbox.

How many miles are on the engine?

For absolutely everything I'd have thought you'd be looking at 2.5K plus.

Hope that helps,

Neil

P.S. The airbox can be modified to fit other frames.

[Jeremy 748R]

I had a feeling that the 748R frame was different.

Do you know if you could fit the 748R engine into a 748 frame and run it with the 748 airbox, throttle bodies and injectors, with the 748R ECU?

Doesn't the R use overhead injectors rather than the "normal" setup on the others?

[JPM]

748R has shower injectors yes

[Jeremy 748R]

Yes, the shower type injection. Looked very cool at ItaliaMoto when they ran the bike with the tank off, and you could see the injectors squirting into the throttle bodies and the fuel rolling over the butterflys. Or am i just sad?

Yes the frame is slightly different.
we have put my 748SP engine in a 748RS frame before and run it using the 748RS injection, although ideally a new map would be needed.
To do it this way you need to use the inlets off the R as well as the inlet rocker covers. An alternative would have been to use a airbox off a Foggy Rep (Kyalami Frame) and either 916 or 996 injectors and throttle bodies, harness, and ECU

engine mounting bolts are also different in diameter but sorted this with spacers usin the bolts from the 748.

to run the 748R engine in a 748 frame should not be to much of a problem, but it would be better to run the 916 injecion throttle bodies along with a 748 or 916 harness, 748/916 airbox, 748/916 inlet manifolds. You can use the 748R ECU fitted with the appropriate chip and I would suggest using the 748R's original 50mm exhaust system

[neil748r]

I guess you could fit the engine and run it with stock 748 TBs, airbox, ECU etc. Not having done it I don't know if there are any litle details that might present a problem although the obvious one would be getting the fuelling to work properly. You'd almost certainly be into the realms of custom mapped chips and/or Power Commander.

To be honest, it's not really that big a deal to mod the lower part of the R airbox to get it to fit other frames. At least that way you'd know everything would work right off.

Basically involves cutting a slot in the bottom of the bottom half of the airbox to fit over the "X" section of the frame and then fabricating an aluminium tunnel to cover it which you then rivet and bond on to reseal the airbox.

You could of course cut out the stock "X" section and weld in a 748R replica section. Bit more work involved though!

Cheers, Neil

I think it's worth naff-all Jeremy and you should give it to me free-gratis

boo-hoo!!!!!!

sharp implements at the ready....!!!!
