Hi, I just got the right chrome cover that is replacing the plastic one on the right side. I'm a little bit confused because I see the gap between the clutch cover and this chrome cover is very small, the cover actually sits on the clutch cover. Is it the way it should be? See the attached picture. Thanks, Corneliu

If you don't want to invest too much changing rotors, using high perf sport calipers, designing adapters and so on I'll recommend you to: rebuild the masters cylinders for both front and rear brakes, switch to steel braided lines, rebuild the calipers (pay attention to the wear of the cylinders) and switch to CL brake pads. It was told me to try Nissin but they were not available immediately. Giving up using EBC, Ferodo, Goldfren and so made a huge difference for me. Delinking the brakes in my opinion is just a matter of personal option.

Did you used OEM gaskets or Athena? I once used Athena gaskets and after one month I had to use instant silicone gasket to glue the valve covers and stop the oil leaking.

Yes, it is heard mainly on decell and it is heard on the lower side (not left side) of the engine. It is not a high tonality sound like the cams sound or a timing chain sound.

Dingy, that block has been replaced. This story is closed now.

Thanks. The knocking was present before replacing the bearings. The new bearings were fitted based on the crankcase/crankshaft/connecting rods markings. The timing chains had been replaced also. Trying to hear exactly the source of the knocking with a stethoscope I found out the noise is coming from the lower side of the engine, approx. from the crankshaft area. Also, the knock can be heard as soon as the engine get hot, not immediately after starting it, and yes, I tried 10W40 and 20W50 mineral oil. The knock is lighter if 20w50.

I have a knocking inside the engine. It's being heard especially on deceleration. The plane bearings on the crankshaft had been replaced, also the connecting rods bearings. Any ideas? Also, the crankshaft (together with pistons) from the 2nd gen venture would fit 1st gen? Does anyone has any experience with that? I know the PN for crankshaft and pistons are different, but from pictures, those looks to be the same.

As I promised I am back. I checked the choke, but it was fine. I replaced the air cut off diaphragms then I did a carb re-sync and now everything is as it was supposed to be. Thanks for your help!

I'll replace the air cut off diaphragm on tomorrow. Float needle leaking and jet block gasket... I'll check them tomorrow as well. Thanks. I'll come back tomorrow with news.

Hello, I have two carbs with this symptom. It is so rich that if I totally close the mixture screw I'm seeing the engine idle is increasing. The same if I'm removing the blind plug from the carburateur joints, the idle rpm is increasing a lot. Also the spark plugs are black. Can someone to advise on causes for very rich mixture? The facts: The large diaphragms have no holes and the sliders are moving freely. All the jets are clear. The air cut off diaphragms have one small hole (each of them actually, on all 4 carbs). Might the air cut off diaphragm be the cause for very rich mixture? What else should I check? Thank you!

Your mirrors are still available as new from the dealers: right mirror http://www.boats.net/parts/detail/yamaha/Y-26H-26290-01-00.html left mirror http://www.boats.net/parts/detail/yamaha/Y-26H-26290-11-00.html

Ok, the crank case just arrived. Some painting needed but else is in excellent condition. I hope this time everything will go fine with the engine.

I see. I don't have a RSV crank here so I can't do any comparison. It would be nice if the pistons will fit. I tried to look also at different pictures on the internet to compare the pistons and crankshaft from VR and RSV. They actually, from the pictures, looks to be the same. I think maybe they're made from different alloys, not necessarily they have different shapes and sizes. By the other hand, I just located a cheap a crank case that apparently looks good: http://www.ebay.com/itm/191030092943?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Could you please take a look at it and let me know your opinion if this piece worth or not? I tried to ask them for more pictures but maybe due to language barrier (because my technical english is far to be perfect ) I had no success. If you can find out more from them it would be very useful for me. Thank you. I really don't understand what exactly means "fire damage" in their description. I'm seeing the same at another item http://www.ebay.com/itm/89-Yamaha-Venture-Royale-XVZ1300-1300-HEAD-CYLINDER-VALVE-SET-/310754306651?pt=Motorcycles_Parts_Accessories&hash=item485a666a5b and wires from the coils melted in another picture: http://www.ebay.com/itm/89-Yamaha-Venture-Royale-XVZ1300-1300-COILS-COIL-/190910692099?pt=Motorcycles_Parts_Accessories&hash=item2c7329fb03 but it is not clear to me if there is something wrong with the crankcase.

I don't think so, because the engine is still 1300cc and the rings are the same so the crank should be similar. Also the crank bearings are the same...

Gary, I finally decided to go with crankcase replacement. In the same time, I'm just wondering what if I'll rebore the cylinders… but I'm seeing the PN for pistons are marked as obsolete. Looking at the later models I see the rods are the same, the piston pin and bolts are the same and even the piston rings are the same, but the pistons have different part number now. Do you have any idea if the 4XY-11635-00-00 (from RSV) can be used to replace 1NL-11635-00-00. What are the differences between the two? Thank you.
