  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Hi, I'm covering some old ground here, but hope with your help, to string your input together to make the right decisions.
My bike is standard, I'm an ok rider, doing enduro practice days, the odd enduro and weekends away to more extreme riding, in Wales, Cornwall etc (in the UK).So its woods, mud, water, rock, steep inclines rather than open fast riding, although it crops up.
On the slower stuff I stall more than I like. So I am considering changing the gearing, lower on the front to 14 and maybe 52 on the back (standard 15/51). Also the TC air box to push more air into it, and maybe aJD Tuner, which I know is very popular on here, but will it help my style, more instant power to lift the front over logs and rocks. Or am I going the wrong way and will make to much power for UK conditions and my type of riding , maybe just the gearing?
All your views are appreciated.
 
Hello Motomanic, I use the gearing you are suggesting there, 14/51 which works great for me on the 511, even in open desert. The TC air box mod is for high rpm and it seems from your post you are looking for low end boost. Is the stalling you are getting from flame outs or just low speed stalls? I have had great success with just the BMW #3 maps installed (Akropovic maps). Which exhaust do you have installed?
 
Hi, low speed stalls. The Akropovic is fitted with Race Map showing and the' Lamba' sensor removed.The TC air box would improve power when I open it up. See where I'm going here, I want it all, improvements to make the perfect bike, its good out the box but reading here its capable of more.
Whats the BMW*3 maps?
 
JD Tuner is the best power for $, power commander/auto tune is the best for power and reliability, but costs a lot more. Stock Akro system is choked up and heavy on TE's, look for a another that is more open. Not sure if FMF still makes mega bomb/4.1rct, but the best for power and less half cost of Akro evo 1.
 
With the gearing , Im leaning towards 14/52, which if a JD tuner is fitted, I am assuming top end would not be any slower than standard?
 
Ok, so only dropping 1 on the front and staying 51 on the back instead of 52, would leave the top speed alone but would it increase the instant go that i want enough,with the JD tuner installed will it lift a lot easier of the throttle?
 
Ok, so we know how changing the gearing will improve the slow stuff and improve immediate lift, but where does the JD Tuner fit in? Is it worth having, and changing the gearing, doing both, will this be so noticeable that it feels like a different bike.And fit my type of riding?
 
JD gives more power. Some people use it to richen up their maps to avoid flame out stall issues.

Click to expand...

The 511 is capable of reaching gearing/rpm limited top speed, so any lowering (smaller countershaft) will lower your top speed...as Tinken said about 6-7 mph for 1 front tooth (or for 3 rear).

The JD helps remove lean surge issues and adds more fuel on top so you will have better acceleration, more predicatable throttle response, and more total power; but the top speed isnt likely to increase as your limitation is RPM/gearing, not power. If you raise the gearing (bigger cs or smaller rear sprocket) at some point you will get to where power/wind resistance becomes the limiting factor, but unless you are wearing a sail that shouldnt be the case with the stock gearing or any lower gearing (ie smaller cs sprocket).

It is hard to find dirt riding where the stock 15/51 is optimal as the top speed is too high. I ride a lot in open desert terrain and I run one tooth smaller on front which means I can make use of all 6 gears and the lower 1st is handy for tight stuff.
 
Ok I've got my wallet out.
I bought a 14T front sprocket and ordered a 52T rear Supersprox, and ordered a JD Tuner from Motorsport. If the gearing isn't what I want then a cheap fix would be a 15t front with the 52T back, this gearing with the JD should lift the front quite easy. Now will a TC air box improve this, or a waste of money?
 
I ride in the desert and am not willing to give up the extraordinary dust avoidance of the stock design for some high rpm power. Tinken rides in the desert and uses the TC box. Personal preference and priorities.

But if your in UK then dust probably isnt an issue....dont know about moisture, but I dont think much spray gets up there.
 
Me too. I want the extra air, for more power, but not at the expense of more wear causing stuff in my engine,
Plus water is often present.
