What are you looking to do? I'm a little lost here- do you have a Sprint with 34,600 miles on it and a spare motor, or did you buy a motor just to rebuild?

Cheers,

Is there something wrong with the motor you bought? Rebuilding a motor gets pretty pricey pretty fast. If you don't already have a torque wrench, I can't say enough good things about my AC/Delco 3/8" digital unit. It was about $110, and money well spent. It handles all of the low torque fasteners up through the medium ones. It maxes out at 50Nm, though, so you'll need something else for things like the head bolts. I have an Eastwood digital 1/2" wrench with angle torque meter for that. It's finicky and annoying to use, unlike the AC/Delco, but it's nice to have the angle meter for the third stage of the head bolt tightening sequence. That one was about $125, IIRC. If you're going to cheap out on one of the torque wrenches, make it the heavy duty one. The smaller one needs much higher precision.

Gaskets and such will also cost you. Last I checked, a full gasket kit was about $350, though you might be able to spend under half that just replacing as needed. The head gasket alone is maybe $60-70 and absolutely necessary.

I strongly recommend having the head skimmed if you pull it. Sucks having to stop every 100 miles between Utah and Texas to top up the radiator and add another stop leak tablet.

Generally, you want to rebuild a motor to fix a problem. Doing it right requires lots of time and money.

The Haynes manual is what I would use if I had to pick one, but I'm lucky enough to have the factory one as well.

Happy to answer your questions, but I feel like the best advice I can give you is to leave it alone if it's working as-is.

Cheers,

Dont have the engine yet, its on its way
over the past 2 years I have rebuilt my bike and all thats left is the engine and electrics.

As much as anything else this is about me wanting to rebuild an engine.

I will be going slow and learning as I go. I rekon it is going to be around 700 pounds all in dont know what liners and pistons will look like. good advice getting the head skimmed thank you
dont know whether to swap engine and have the benefit of testing the new one, also, this means I will rebuild the matching engine,(to frame)
This is my one bike and I would like to keep it on the road while also having the other hobby of building in the shed Im starting to build up spare parts and as I move on I may decide to build second bike,frame for 100 on ebay.
I have a couple of torque wrenches up to 140 I think, Teng tools.

Probably need pullers,

I have a haynes and a workshop manual, and with a spare engine, I can take my time and move forward slowly, so this it good news for,my wallet and my stress levels
my bike is 34600 and running like a swiss watch, the spare engine is 25000,
reading this back it sounds weird, to rebuild a healthy engine, only,I cant afford new bike and this way I end up with a new engine, and I learn something in the process .

So far with new bearings, rebuild calipers, master cylinders powder coatings new panels discs pads and various bits and pieces I could not recoup my money.
I will end up with a new, (in all but name,) bike

Any dealer should be able to get it for you. Part #T3990058; Ling's lists it at £225.
