Was it imported into Ireland "still in EU Or Northern Ireland "not in eu" As the required paperwork & fee,s to reg in UK will be different Headlight chuck a blandit light on and a cheep MPH speedo to get over that hurdle initially

find the 2 that are the feed and earth for the bulb and just use those

well i would say the fronts are connected to the wrong wires in loom

my 1216 busa piston job looks exactly the same on a bore scope

It,s quite hard to get a decent reading these days with unleaded fuels.... i use NOS Suzuki branded plugs which i think are Denso ...... i would start with a new set of plugs .... and a bag with what you need to get them out and a decent thrash down a long straight kill ignition coast to stop and pull plug's are you sure its 1216 and high comp ? slugs look very flat .....

Don't hold ya breath he's not been online for 3 years

I know there are not that many owners on OSS however for those there are i found some online parts books GSX 750 Zuma https://www.bike-parts-suz.com/suzuki-motorcycle/750-MOTO/GSX/1999/GSX750X-E4-/1560 GSX 1200 Zuma https://www.bike-parts-suz.com/suzuki-motorcycle/1200-MOTO/GSX/1999/GSX1200X-E4-/1286 The Site https://www.bike-parts-suz.com/ also has all the usual suspects on it as well including some grey imports It's an offshoot of Streetbike Dudley so they won't actually have the parts in stock and will only get them from Robinsons or Suzuki GB SO the best bet is to use to find the part no,s then order from Robinsions with OSS discount There is also an excellent cross ref feature on Fowlers https://www.fowlersparts.co.uk/ to see what other models use same parts

Many Moons ago Centreline used to do road versions of there race wheels which were bolt together The road versions had bolts but were not bolt together wheels they just had a drilled flange like your pic

And Cams are forgings not castings as a rule

blow the pic up you will see the lobe is worn ......... i,m sure the seller said its fine "Kercing ££"

That lobe is F##Ked

Its worth moving the coils to the same place as a 1200 Zuma as well

Loppie did one using a sealed stock airbox as well just for fun as someone said it would not work

I don't recall Dresda making swingarms ..just frame kits But yeap defiantly a Period Davida Arm .

He was on Faceache as well

It can only fall out if you take the sprocket cover off 6mm S/Steel bar grind a dome on the ends

Even though it did ...It was a HP mod the Clue is in his name Revshotclutch also did it was an article in Superbike Mag

not much in it 4V a few Kg heaver

Even with an oil boiler in those frames are not very doing engine work friendly

To stop oil swashing away from pick up common in the later water boilers when used in sidecars

i,ll be careful when I remove it then

Similar Spec to mine Head on mine was done by Dom Trickett And i need to remove the spacer from its brief turbo & Nos Time

As I understand it "its well known that Bob was stubborn" so it was done with a bit of butchery and adjusting the engine position slightly it only need a few mm of clearance as if you look at a close up pic the frame / rear mount slightly encroached over the case ... Bob supplied a longer stiffer arm with drag slots for the revised lowered version of the bike and i think he tried a set of raked yokes in it as well Apparently when he ordered the beam frame it was built with clearance for the lockup spacer "I bet that was a very abuse laden conversation" but that said he did a lot to promote Spondon on a coax its a huge problem to overcome as the cover / engine is behind the arm pivot ... . so best not to go there Yes Jimbo with the Yellow Harris turbo had to have his frame modified for the same reason I think there's a pic on here pics are here unfortunately some the pics are photo bucket overlayed since he originally posted but still viewable and there are clear ones on page 3

Ok real world comparison my 1166 EFE forged pistons welded crank lock up proper built motor . Garrett T3 "external gate" Tractor Carb "HSR is no better in BHP stakes" this was a quick favour Tim Blakemore did for me to check the fuelling with a 6PSI spring 159BHP with top end blips on the curve "later traced to a split Dyna Coil once home" we only did the one run due to time and not wanting to take up Tims Dyno Time messing about with it ... So 10 down on the Rajay Once i had it sorted it made 175 at same boost....so a huge 5 bean better
