El Gringo Posted December 21, 2018 Author Share Posted December 21, 2018 For a winter project this is going rather well, Motor is out for a coat of paint, and the covers will be off to the coaters after the festivities Chassis is all built back up ready for the engine to go back in 3 Quote Link to comment
El Gringo Posted January 15, 2019 Author Share Posted January 15, 2019 (edited) Aye up, still going on this, just awaiting some more bits back from powder coating Cast your minds back about 12-18 months to when i finally got it to run relatively correctly - i'm not sure if I ever mentioned it on here but during the process i tried running it without the turbo on and had the headers only loosely bolted up using the outside 2 bolts. It fired up a treat but was suddenly pissing oil out of the front of the engine, seemingly from the upper exhaust stud hole on cylinder 3. With a bolt in it it didn;t so much gush as weep a fair bit - i put this down to a ham fisted previous owner having cracked the head putting an over long bolt in Now i've got the engine on the bench i had a proper look - what i found was less than amusing At some point someone has snapped that particular exhaust bolt, then tried to drill it out.................................... Whats that...... It can't be can it? Bugger me it is! Drilled off centre, on the piss and all the fucking way through! This should demonstrate just how far off straight it's been drilled! So, rectified with a spot of Belzona for now Now just awaiting a decent clean and a coat of paint I've also spent a small fortune on some more Ti bling for various bits, cam cover bolts, sprocket nuts and a couple of other bits. Also bought a manual cam chain tensioner to be on the safe side as i've got no idea of the heritage of the existing one So, hopefully in the next couple of weeks if it warms up enough to paint, it'll be done and back in for the final build Then we've just got to hope it plays ball during testing Edited January 15, 2019 by El Gringo 2 Quote Link to comment
Gixer1460 Posted January 15, 2019 Share Posted January 15, 2019 Wonder if the 'engineer' doing the drilling said ' oh bollocks' when the drill chuck hit the exhaust port.............and did he fetch out all the drill shavings - Hmmm what do you think! 1 Quote Link to comment

It does explain where all the bits of swarf that were in the sump the first time i took it off came from! Fortunately, this second time round it's nice and swarf free As you say "engineer" 1 Quote Link to comment

Unfortunately i've no idea which of the 16 previous owners it was. I think it's had a troubled/hard existence Still, onwards and upwards, i've got a spare motor now which is always a bonus and i've been doing some reading up on using FZR600 pistons which will give it a bit of a capacity bump so at some point it'll probably be getting a mk2 engine Edited January 16, 2019 by El Gringo 4 Quote Link to comment
El Gringo Posted January 29, 2019 Author Share Posted January 29, 2019 All going according to plan so far Engine is back in, body work should be back at the weekend. Carbs need another clean and i think i'm going to go back to the 100 main jets - then it's a case of connecting everything back up I'm still a tad concerned about it not transitioning on to boost properly but i think it's just going to need a bit more testing - there are only a finite number of things it can be now I've added a take off to the plenum to feed the fuel pressure regulator, and i'm looking at making s series of restrictors for the pitot tube so we can try smaller bores to see if that helps I've also made a little plate to hold the choke bar closed to rule that out 3 Quote Link to comment
Blubber Posted January 29, 2019 Share Posted January 29, 2019 Nice - can post a picture of the choke bar plate? And...curious if you can still use the choke (or use the software for cold start enrichment ) 1 Quote Link to comment

And...curious if you can still use the choke (or use the software for cold start enrichment ) I'll take you a pic later @Blubber- It's nothing fancy, a bent bit of 10mm wide steel flat stock, there was a "spare" casting on the end of the carbs so i tapped it to M6 for a bolt. Choke works the same but you have to manually put the plate over the end of the choke rod and do the bolt up - just need to remember to take a 5mm allen key everywhere with me It's only a temporary measure to see if that's part of the problem, if it helps i'll make something more permanent 1 Quote Link to comment

El Gringo Posted February 6, 2019 Author Share Posted February 6, 2019 (edited) Quick update, should have the bodywork back this weekend, so in the meantime i figured a proper exhaust might help with the possibility of getting it MOT'd Also been through the carbs again and given them a good clean - looking much tidier now One thing that i did notice that might have quite a large effect on the transition - where the tees feed the float bowl vents from the pitot tube, the rubber is very soft and doesn't seal very well over the stubs. I've now lockwired these to try and seal them a bit better but it's not ideal. I did have a read back through the spondon bandit thread and found the mod using the outer feed points but i don't think there's enough sticking out to get a good fit on the 400 carbs (plus i can't get the bank of carbs apart to fit the cross pieces between the stubs) - might be something to look at in the future Edited February 6, 2019 by El Gringo 4 Quote Link to comment
El Gringo Posted February 11, 2019 Author Share Posted February 11, 2019 (edited) Right then, ta dah! Nearly done, just needs fluids, carb balance and final bolting together Edited February 11, 2019 by El Gringo 6 Quote Link to comment

Definitely, although i want to test it somewhere again beforehand to see if it's helped and to save wasting more time on the dyno. Ian Cross invited me up to theirs to run it so will let you know as and when Quote Link to comment

It possibly would, but unless you've got the carbs aparti can't see how you'd get them back in. Mine need the squishyness to get them between the stubs. Ideally i'd take them apart and make a soild joint across and the drill and use the outer unused connections (as per the turbo spondon bandit thread) but i can't get my carbs apart I'm hoping the lockwire will at least hold some of the boost in Quote Link to comment

I was wondering if i could tap the bit that is there out and use a threaded fitting with a hose barb end to give it something a bit more positive to connect to but decided to try lock wire on the normal rubber tees first Quote Link to comment
