New vs Old Model

[leevtr]

Not sure if this is and old subject...

I am aware that the later storm has differences in power than the old one ( or so I thought ) and I was wondering where Honda made the changes.

The reason for asking is I just fitted DJ kit to my 1999, as per DJ recommendations, which were 180 jets in both carbs and mixture screw 2 turns out from seated, needles set on 4th ring.

Seems to me fine, pulls really well everywhere. Would these settings be the same on a later model ?? Or were the changes in power from old to new model, alterations in the fuel delivery ??

I think you will find the slight loss in power with the later ones came form the later emissions added to it, so no biggie. I have still yet to work out exactly what the differences are regarding emissions and possibly carbs.

I did have a link somewhere that listed the difference between the early and later models. I will try and find it.

I think the later models faster haveing had a r reg before this one seems more off the mark and off.or if I'm wrong there can't be that much difference

[VTRDark]

With regards to power the differences are negligible. A new model would feel like it has more if it was compared to an older worn out storm that's hard a hard life. But on the other hand A well looked after early storm with low miles and has had an easy life would seem to have more power than a later one that has had a hard life with high mileage or is Blue. The best thing with the later models is the slightly bigger tank and clip on angles changed slightly for more comfort, also the fork upgrade.

My querie is to wether the carb settings are the same or not.

As for worn out....my old storm was showing about 38,000 when dyno'd at 115. DSD figures, not mine.

The carbs themselves as far as I'm aware are visually the same. But Honda say there where minor carb and ignition changes. So they may have tweaked some of the internal passage ways inside the carb. But as far as jetting and carb settings go it will differ slightly from country to country and changes in altitude, humidity etc. As far as the UK goes I think they put a 48 pilot jet in as standard whereas some of the early models had a 45. A 48 pilot could be the minor change they talk about.

That don't mean anything. TBH unless there had been some internal engine upgrades ie cams, pistons 115 is a bit optimistic for a standard Storm. Maybe the dyno operator massaged the figures for you. Quite often dyno runs are only for bragging rights "my Storm has more HP/torque than your Storm" type of thing. Customers are usually more interested in max HP and not driveability. Or maybe the dyno had not been calibrated that day for the weather conditions, temp, humidity, altitude, etc. There's too many variables involved with dyno runs.

Yeah I was surprised at 115, but it was the same dyno that showed 127 for my SP1, and that had full system, PC3 and K&N's. and that's not a particularly high reading, so who knows.

My point was I don't think just because they are old and have a little bit of mileage on, they automatically get tired. Personally I think a well looked after and maintained Storm will probably make more power at 30k than one with 5k on the clock.

One of the bike mags, or MCN, did a comparison between 2 identical bikes. One was run in as per the makers instructions, the other ragged from the word go. The one which was used hardest produced a higher power output and felt looser.

[rob...]

honda say they changed the carbs and ignition a bit on the later ones..... carbs are about £50, the 2 ignition boxes can be got for about a tenner a box on e-bay... do a back-to-back on the same bike, on the same dyno, on the same day.

[leevtr]

Only asked because someone with a later model asked about jetting, and I got to wondering if my settings would possibly work on theirs.

[Stratman]

Older models made more power, later ones have blanking plates in the inlet tracts to smooth low power delivery. Earlier models tested in Bike and MCN with a top end of 155-157.5mph, later ones 144 mph.

Lee, I can't really add anything to your carb question, but as others have mentioned the earlier ones (16ltr fuel tank models) did make around on average 5bhp more than the later ones, going by what the bike mag tests showed between the two.

and if its an early black one you get lots more than a newer blue one

[playerone]

got a new model red and old model black and although its about a year and a half since I rode the red one, it doesn't feel like there's much difference between them

It's not going to make a huge difference with those two models, as the Red one is fastest regardless only kidding
