RPM. I idle at 1000 RPM and drive at 2300 mostly is it bad?
I hear a lot of guys running their bikes at 1500 to a min of 1200 rpm. I wish I had taken a video of the bike at idle when I got it. I always ride around 2200rpm because in japan the limit is usually 40kph or 20 mph. I know im out of the power band but is there any negative to this? gas mileage, chain wear thumping a rod out of the block?

YES its not meeting its destiny!!!!
missing the noise, not the vibes. However never say never!
Re: RPM. I idle at 1000 RPM and drive at 2300 mostly is it b
no problem with it, the CBF will idle around town in 6th at 25-30, my dad's CBF judders at low revs where mine doesn't. So I would say it's dependant on the bike and if it likes it, I would have thought the storm would judder at those revs, can't say I have tried.

Ha Ha ha. That is the best. Well I just plugged a loose breather pipe in and she idles at 950. no pops farts or hesitation. Ive been told to balance the crabs but dont have the hose to do so. Believe me I hammer it when I can.
Just cleaned and lubed a dirty throttle so now shes in great shape.
She gets cranky below 2000.

Red,
It's a shame the speed limits are so low in Japan.
Out here in Oz we have mainly 50,60,80,100,110,
I have standard gearing on mine , what do you have ?
The VTR doesn't run well until about 3500 Rpms in my experience. Sustained running at speeds below that are hazardous to the engine by way of stress on the crank etc.
Better to ride a gear lower and sit on about 3500 to 4000.
Try it and see how you go. V Twins are different to IL4s .
Let us know .

Re: RPM. I idle at 1000 RPM and drive at 2300 mostly is it b
2000 rpm should only be seen as you move up through 1st gear. At that engine speed you have no throttle response and are lugging the engine, potentially knocked the big end bearings out. Spin the bugger and keep the oil pressure up. You are also not saving fuel at low revs.
Storms are fairly high geared. I ONLY get out of 4th on motorways and dual carriageways and on 60 mph country roads I rarely get into 4th.

Re: RPM. I idle at 1000 RPM and drive at 2300 mostly is it b
I've had no problems with the idle speed that low, but the workshop manual recommends 1200...reason being that the oil pump has to push the oil around the engine and up to the top and lubricate all parts. The only reason guys idle at higher than 1200 revs is because of bad tuning and the bike cutting out as the revs drop or to get around a snaggy clutch. If you are capable of idling at those low revs without any stumbling then it's a good sign that your pilot circuit and fuel mixture is good.
My revs get a bit higher when riding though and I don't lug it which can put unnecessary strain on the engine, but this is a big V twin and I'm sure with the torque it can cope. Engines get used to way they are ridden so it may feel a little unresponsive if it's not used to getting the revs up and having a good thrashing which loosens things up. You may even find that you use more fuel with the engine having to work harder. On the other hand you don't want to thrash it too hard all the time as that also adds wear and tear so it's a case of finding an even balance. That's why we have a gearbox. Anything below 3000 revs these bikes don't particularly enjoy and may be a bit jittery. Get the revs up a little and run on the needles and the bike will thank you for it. It's not a Harley.

Re: RPM. I idle at 1000 RPM and drive at 2300 mostly is it b
My net crashed before I could post my last reply. Thanks guys. Harley's ain't meant for it either as Ive read thats just owner ignorance. I wasn't sure but I trust you guys. I am a car engine builder by long ago trade and thats why I asked. I actually got the idle down to 950Rpm and as long as my oil light isnt coming on and the noise from the top end stays non existent ill keep it.
Long story short. I tuned it by ear from what I learned from a great race engine builder I know his skill has been proven many times on the dyno and track side. Plus I didnt have the hose to do it propper. Two bottle style.
Im gonna go count the teeth. I have a nice gold alu sprocket that came with it.
Bikes acting strange in a good way. So I got antsy tonight after pulling the airbox again. Its pretty cool here for summer. I got on the bike and puttered through town. cracking the throttle just a hair it goes up to 3000 so thats where ill run it.
The story, I went 5 miles and the bike still wasn't fully warm but it was pretty well. I turned around and got to my only straight within a decent ride. I pulled over let a car that was riding me pass. I clicked it into first checked everything and got rolling. I never hit 9k before and wanted to just see. I leaned forward belted it from 3/4 at around 50kph. front end lifted I let off tire came down I hit it again tire came up. not the cool wheelie kind. I was going too fast for me with no wheel on the ground maybe 8cm 4 inches off the pavement. I hit 9 as the tire touched down again and went to second. I gave it 3/4 and the front was super light around 140+kph it came back down and I hit the brakes. its a short straight. I also still had low temp.
MY question is do you guys think its modded up or just the gearing?
Bike was not this mean before.

Well Ill look again tonight after work. back has 40 or 41. I only double checked and got 40. so I bet I missed a tooth. Ill pull the clutch cover as I did clean it but not that well. Ill count the front. on another forum a guy said if its running good that it'll pull like that. Funny what the tps and a filter ll do. I did play with the balance but only by ear.
Re: RPM. I idle at 1000 RPM and drive at 2300 mostly is it b
What do you mean do it proper. You did do it the proper way.Long story short. I tuned it by ear from what I learned from a great race engine builder I know his skill has been proven many times on the dyno and track side. Plus I didn't have the hose to do it propper. Two bottle style.
As for the bike maybe it has no rev limiter.

Re: RPM. I idle at 1000 RPM and drive at 2300 mostly is it b
I think you will have to live with lifting the front wheel if you give it a handful in 1st and 2nd, it's a trait of the bike. I can get even get the front wheel up if I roll off and snatch the throttle open in 3rd without using my body weight.
Tony Mon's when he had the yellow one with high compression pistons and mods, the front would go light with throttle full open in 5th.

Re: RPM. I idle at 1000 RPM and drive at 2300 mostly is it b
Well Carl bad news on that no rev limiter. I dont think I did any damage but my throttle cables bind up when I make a hard right. I lubed em proper. Bar oil all the way. I think I kinked em trying to slide the grip off with them bolted to the bike.... 
I blipped it to annoy a buddy of mine and the revs went up to oh my god. Last I saw was 9 and didnt bounce.
Bikes was making noise. A bad whistle kind. I think it may have been the CCT's getting a run for the money as it did go away but 950 to oh my god is not good on a lukewarm engine.
Id take her to 10,000 if I was racing proper but not a cold engine.... I have done this in my youth to a less well maintained vehicle only to tear it down the next month to see what it means to spin a bearing. I doubt the honda would but I am worried about improperly expanded components slapping around at 14,000....
I will test it on a as you call it dual carriageway to see if it stops at 10500 if not I will put one in.
On the other side
I love the bike and ill be beefing it up as I can afford to.

They all have a soft rev limiter programmed into the ecu.
Revving in neutral will potentially take it further than that, as will changing down at high revs, 8K+
If revving out in a gear the soft limiter comes in but then a hard limiter stops it revving further by cutting sparks.
Try it, in maybe second or third, nothing bad happens.

It's not falling off, it's an upgrade opportunity.

I was referring to the Japanese limiter which the bike is so would be lower than what we have.They all have a soft rev limiter programmed into the ecu.
