They are shorter and fit the stroke of the 1000. Also maybe people don’t look further than the end of their nose.

Gs1100g/gl shaft drive rods.

Same part numbers for both 1052 and 1127.

@Reinhoudthanks but I have 1 complete motor and a bottom end spare. In fact I’ll be selling stuff off soon as I need the room. When I get cranks built I use 494 rods. As strong if not stronger than 493

I bought two sets when I did my crank.

1200 bandits have a big weight mounted between the coils up by the head stock as an anti vibration aid. Maybe something like that would help.

Yes I’m shure. There’s a point on the end of the guide that locates in the hole on the ally piece. If not there is too much pressure from the chain when running and it will fracture the steel piece of the blade where the bolt hole is.

@Reinhoudthe rear blade also locates in that too.

@FJDif it is a gs1000 8v? Block it will give you roughly 1240cc @ 78mm. Imo it’s on the limit and will have very thin liners. I considered doing this but for my road bike I went with 76mm Kawasaki Pistons from Mtc. Even using gs1100efe liners I had to hand relieve the crank cases. Using any liner that is bigger on the od than a efe liner makes the block very weak and will window out into fresh air between the cylinders, with that you get oil leaks and a very unstable block with which ring life will suffer.

Up near Cortez 50? I’m in Dunedin.

@v-twinwalkerwhere on the west coast are you?

I havnt used one as I usually go stupid big lol. Used to work at MRE and we used to do a lot of upgrades cc wise.

If you are going to use an 1135 ef cylinder you can go 76mm (1198) which for reliable use is a good upgrade. Still leaves the liners with enough meat in them. MTC do a piston kit for this and it comes with a cometic mls head gasket, and use a Suzuki 1135 base gasket so keeping it all sealed up well.

Gsx1100f ? Maybe. They are 275 od 6 bolt.

@manden Base circle is 1”100th (28mm) cam bearing diameter is 22mm overall length of cams 13 3/4 inches. Cam bearing centers from ends of cam going towards ctr of cam below sprocket side 1 1/4 in. Then 4 1/2 in. Same for other side. 32 tooth cam sprockets dont know if they will for an RF900 but I suspect they will. Buckets and springs are the same part numbers. Good luck.

I would say the busa arm will fit. The one in mine is a srad750 with gsxr1000 08 wheel and I don’t see any problems with the chain run. I am still going through the rear shock and linkage saga but I think the gsxr1000 07/08 shock and linkage is the one I will end up using as in pic. Bushings need making for the linkage pivot eye on frame and also 6mm spacer to space top shock mount out from frame. Its not easy getting a 1250 in a 750w as no mounting point on the frame is usable for the engine. Therefore lots of setting up and measurements and new mounts to make. Also chopping the bottom frame rails. When I had engine in the right place I started by fixing the front engine mounts as these were just two plates and then it allowed me to orient the engine. As you can see in the other pics the engine mounts are way different Hope this helps @Andyg

1100w has same con rod big end as hayabusa no difference in shell part numbers. Same shells in 1100gsxr/1200 bandit/ hayabusa and 1250 bandit. 1250 bandit is already 18mm little end.

Only 4mm difference. Not insurmountable.

Bim? @Captain Chaos

1250 is a better motor IMO than 1100w

@mandenalthough the stud spacing is the same the 1250 block has 2 bolts at the front in the camchain area and is wide at this point. The 1100 has only one bolt at the front and much narrower and my feeling is would not seal. The 1250 head uses same size valves,springs, collets, and retainers as 1100 (part numbers same) there is room for port work as with the 1100 1100 cams won’t fit 1250 as cam bearing sizes are different.

@Gammaboyon Sunday or Monday I can give you measurements of block and head for 1250 if you need things like stud spacing and block height etc. 1250 crank won’t fit 1100. The rod bearings are the same but mains are smaller. Also crank gear is much larger.

In the last pic with the number at the end of it says RC it could be an RC engineering exhaust.
