Attention to detail is spot on with this one! That will be like a show piece when you finish
Wish I had the patience to be that in detail with mine
Thanks, knowing it isn't particular low mileage or going to be completely original means I can still use it without too much concern. Let me know if I can do anything when you get on yours. I can get some discount on most parts, particularly engine stuff. Also just a heads up if you are thinking of replacing the crank Suzuki are currently making a batch and not sure if they will be making more after that, they will be ready early Feb and will most likely come with a decent price increase so get your order in now if so!Wish I had the patience to be that in detail with mine

Brilliant.
The RS250 was almost mythical to me when I was 17.
Very rare sight on the roads but I used to go to my local Aprillia dealer just to gawp at one and dream.
Remember in my early teens when a Dad's friend had one locally, used to always be over when I heard his garage being opened. As with everything like this wish I had got one when I first passed my test as would have been a good investment, although would have struggled to afford to keep it going.The RS250 was almost mythical to me when I was 17.

Great work so far, its easy to get carried away with the £££ ,best not keep count...
Is the gearbox output spline ok, they have a habit of wearing?
Had to replace mine on the RGV.
Keeping a stash of receipts but not going to add them up, although still think I could sell this without a lose currently - which rarely happens with a project like this!Is the gearbox output spline ok, they have a habit of wearing?
Had to replace mine on the RGV.
I had a quick check when removing the sprocket and didnt notice anything, will double check thank you.
Barrels are done so popping to The Tuning Works to collect them in the morning.
Cases should have been blasted yesterday morning so hopefully over the Christmas break I can get the bottom end back together, just waiting on that crank in early Feb,

Appreciate heads up. I'm starting on mine in next hour or so. Just going to strip it to the point I can get engine out in the week. Hoping tolerances are ok on bottom end and it's just pistons it needs
Definitely get yourself on some CBTD once it's rebuilt with other smokers. You'll have some proper good fun

Messed up with me reply there. For some reason I'm not chocolate frog. I'm too thick to work out how to fix that but that was me replying
Will drop you a PM so you have my details, even with pistons, rings, gaskets etc I should be able to help. Looking forward to seeing your progress!Had a go at rebuilding the rear brake caliper at the start of the week, having never done one before thought it best to start with the rear as less to go wrong and easier to sort if I make a mistake but it was surprisingly easy and all went together well. All back on the bike and bled through, works well and isn't leaking any fluid (yet!).
Also got the crankcase back from blasting this morning, they have come out amazing!
Before:
After:
Collected the barrels from Sean at the Tuning works at the start of this week and had a chat with him, he has sold me on the Zeltronics once I get it up and running.
Will get some pictures of the barrels but they have come up well, like the cases and heads, so the engine should look great when it goes together.
Will get the bottom end back together and the barrels built up over the Christmas break so I am ready for when the crank finally arrives - although if the Feb date drops off any further I will be tempted to get it back together with the old crank and then replace it at a later date.

Those cases look mega, do you know what they were blasted with?
Re: Brake calipers it's easy when the calipers and seals etc are decent quality, Brembo are really good at both.
They have been aqua blasted and then clear Cerakoted.Re: Brake calipers it's easy when the calipers and seals etc are decent quality, Brembo are really good at both.
They will go through a hot wash a number of times and all the oil drillings etc thoroughly cleaned out - you have to be careful of any debris left behind.
Yeah, used Brembo seal kit and was surprised how easily it all went together!

Regarding the Zeeltronic, I have one and it's excellent, particularly for PV control.
I also invested in the ign pulse generator which allows me to set the Zeel up with a fake rpm signal which I can move through the rpm range and confirm PV activity at each rpm step
Make
MK3 Dan said:
Thanks Steve,
Think it was you that mentioned it originally, any clues on where your ignition pulse generator came from?
I see it can run the quick shifter, have you tried this?
I’ll check the make but if memory serves me right I think it came from Sean at TTW. Think it was you that mentioned it originally, any clues on where your ignition pulse generator came from?
I see it can run the quick shifter, have you tried this?
And as the ignition pulsers are dedicated to each cylinder, offset by 90 degrees, you only have to plug into one of them to drive the Zeeltronic.

Seriously impressive work
Send me your address and I’ll pop my spare engine in the post
Jokes aside and while it’s still an option, have you looked at the revised 1st/2nd gear set from TTW?
Standard gears are looong between 1st and 2nd and it tends to drop out of the power band until it carries 2nd a bit longer. The revised gears tidy up one of the anomalies in the engine nicely.
And regarding the Zeeltronic, are the ecu side plugs available now to make it easier to connect to the standard loom??

Ha, thanks Steve, send the engine over and I will get on it!! Quite enjoying the rebuild and always nice when it looks good!
Will look at the gears but will start as it is, already strecthing the budget, will see how we go.
The tuning works do the plugs for Zeltroric so its plug and play, no excuse not too really!
Started on the tank this week, no photos but had the tank out and gone through, tap built up with petrol gunk so an easy clean to get it working. Paint was bad but dropped at a bodyshop this morning and a few seconds with a mop showed it should be good once properly gone through. Mould cleaned off the bottom after I taped it up so could steam.
Gave the carbs a clean up and found alot of gunk in the float bowl, again mostly good through just some rubbish from it sitting
Fuel cap was a mess so stripped and sent off for blasting/painting
Random Japanese sweet wrapper found when stripping down the seat unit!
Started looking at fairing panels before they went away for paint!
Had supervision from a furry friend!

Tried cleaning up the front calipers but had no luck, started removing paint without removing all the dirt so they have gone to be Cerakoted too!
Carbon rear mudguard and sprocket cover should be delivered this week.
Still waiting on the crank which is showing 'delayed' with Suzuki so hope that shows up soon, its my biggest halt in progress!

Suzuki! They are having a batch of 100 made that are apparently due early Feb.
Get a huge discount from them through work so not worth looking elsewhere! Also it is my reason for replacing rather than rebuilding, not a lot more to go with new.
I see, be interesting to see how "good" the new batch will be ! Get a huge discount from them through work so not worth looking elsewhere! Also it is my reason for replacing rather than rebuilding, not a lot more to go with new.
All the new ones i have sold have been so far out of true and with loads of dents / marks on the outside.
We have to check everyone and true them up before they go out.
