Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
I installed it in MODEL 94 year of CRM 80. It's set for CRM only, Throttle - Excellent that comes with Wire and Grip - It is Set. Because it is Motorcycle running Off-road to Main, it does not end with Funnel, so it took a bit of trouble to connect with carburetor, including processing of Air Cleaner BOX, but it fell nicely. NORMAL aperture is about 1 for 18 Φ. It's 550 times 28 Φ so it's self-flowing, but the area taken in by Air Cleaner BOX is also 1. I am working to make it more than 5 times. In my case I replaced it with PWK 28 with the pro skill chamber and FMF silencer installed. I think the power of the large caliber special fusion is wonderful compared to the normal cab. Especially the power of medium and low speed has striking things. Regarding the setting, I had read your everyone's impressions and it was a purchase prepared to be pretty hard to work ~. Initial setting is PJ 38 of MJ 135, and I ran as it was for the time being - - It was a good feeling!) It was really good feeling. However, we had a lot of jets buying from the preliminary bubbles so I tried it variously, but it got settled in the beginning. If you say minusPoint you care about Manifold's angle is too tight and the inclination angle of carburetor is anxious. If it is a flat land, you do not have to adjust the liquid level, but it is somehow Large durable dimension, but it seems to over blow on the inclined surface like off-road driving. Perhaps I think that it is an angle that was established to fend off the Oil pump, but this is Minus. View Detail
From the first, since the Helmet in and the Oil pump were removed, they were satisfactory to attachment.The affinity with the Engine tuned up by there being as engine performance has many users is a cinch. However, the Bands of passage metal of a photograph shift immediately.If some are devised, I will think that it is satisfactory, but I am set merchandise and want you to carry out attachment to the structure as for which a problem is not.Since a Setting of minimum [ run / ordinarily ] is needed in use, Jets need to arrange and it needs to arrange with sufficient perseverance.It is by reference of * Setting. Engine: NSR80 Port processing Cylinder .Ignition timing change Chamber: Chamber only for LipsNSR80 MJ:128 SJ:30 Needle: It is the attached fellow and is the 5th step.View Detail
In Ho, the amateur who used it in NS-1, I think that it is difficult to issue firm setting even if it can attach. Although it did together with Ho of the motorcycle store of the impossible smile acquaintance in me, it was said that it was difficult for this to issue setting very much. If the pure twist which succeeded in issuing setting somehow through many complications is also united with a chamber since it differs in a suction amount markedly, it will become markedly quick. I think that it is a thing which can be attached firmly and as for which a thing should just become.View Detail
Since it was small when the manifold hole which was attached to the bore up vehicles of NSR50 and where that it can blow going up is considerably different compared with a normal cab remained as it was, it exchanged for the coincidence processed and extended at the big lead valve.View Detail
The power up cannot be a carburetor too and is ~! Suction quantity of a pure twist is increasing far! Although it cannot necessarily upgrade with bolt-on [ natural ] easily, Do carry out firm setting to expect considerably? Since it is a direct carburetor of race specification, in town riding, they are .., therefore four stars which may be severe!View Detail
