NSR FXR, the new No45

[Henk]

Awesome. What size you up to now? What piston? Cheers.

Surely it's a 250 by now.

[richban]

Sick shit. Does that require cutting a bit of liner away to accommodate the silly sized valves too?

Nah still fit nice. the valve size is limited by there spacing between them.

[richban]

157. Will go like a 250.

[richban]

What piston? Cheers.

not telling.

Just ring his brother....

It all looks very nice Rich. Are there any concerns around fatigue on the piston scallops?
I can't wait to see it fully completed and out there. Its going to be a weapon in the NSR.


But I can't resist (given its KB)..
Don't forget to put a hour meter on it (right from the first start).
Then we can run a poll ("How many hours until Rich delivers another shrapnel bomb?")

Yeah I know that i was meaning how big the valves

No issues with the valve pockets heaps of meat there.

Yeah well its pushing it for sure. High compression, 13200 rpm and still air / oil cooled. A full belly pan might not be enough to catch the bits this time. It would not have helped last time. Intake valves are 25. Top end power will be interesting for sure.

Piston is a Wiseco (opps edit JE piston). Ninja 250 piston. Josh at kelfords spend a day making it light enough to work its still to heavy and the crank needed mallory to sort the balance. They are a heavy pice of wrongness. Josh hates me for sure. Best and cheapest option will be a batch of custom pistons. If you used the piston in an unmodified state without doing your crank it could really cause some problems with balance and you would most likely loose power. There you go some sharing and caring ESE style.

There are so many people running FXRs in you could probably do an order of 25 30 pistons.

looks like your old engine would hit around 27hp at a bit over 13000rpm going of the old dyno run of yours? . l need a new fxr engine to play with but stuff the bro lm going 2 smoker cause l want ot blow up every meeting now

If we got 27hp that would be amazing. Real test will be a back to back dyno session on the ESE dyno. apples and apples.

farrrrkkkkkk that piston work is mint... i got one here but its not been attacked yet.

ermmm that other piston is at work in the outbox. lol, so u will get it eventually.

ur engine is going to be awesome!!

Yeah no way I could have done that. I owe Josh many beers. All good on the piston. Talked to Kevin about an order of custom pistons. He said he will look into it. They will still be 300 bucks each though.

Started on the engine mounting today. Got all excited when the bottom engine mount slid through and sat in there all nice. Quickly realized the engine was sloping to far forward and drive shaft to hi. Pooo. Also looks like the top cross brace might need to go. Will try and save it as I want to add a mount to the back of the engine. Also looked a little harder at the front break should be simple enough with a packer plate and a bit of chopping an welding on the steel caliper mount. Also made a new strong front tank mount as well today. Did a rough weigh in today as well. Piled all the bit i could think of and she came in at 86kg. not bad but will have to make sure everything added to the bike will be as light as possible to say that weight.

Biggest challenge will be when my new Tig arrives next week. First project New subframe. Never tig welded before. Worked with gas ages ago but looking forward to getting stuck in. Second project is to use the FXR frame and remake it better stronger lighter.

[hmurphy]

Looks awesome! Man 86kg is damn light. Mine is 104 with 2 litres of gas. My rims probably weigh a good 100kg though but I'm too cheap to buy expensive ones like you.

Looking mint mate, is the first photo with the motor sitting in the original mount? Because if it is I would say you would easily get away with running that in terms of sprocket position to the swingarm point. Even the motor leaning forward like that should be sweet.

Yeah it is close. Close is close, but perfect is better. Need to look at the angle thing and see if it is an advantage or not. If it means I need more oil then that is a good thing. I am going to hold on anymore engine mount stuff and sort a few more fiddly bits for now. Need to do a proper measurement with 25mm of sag to see how far out it really is. Weight distribution from the rough weigh in was a little bias to the front. I think 44 front and 42 rear. So looking good so far. It is just going to get more heavy on the front. Seat position will be quite far back and quite jacked so I can stretch out across the top more.
