I need some help with a particular conundrum I find myself in, hope that any expert mechanic, can assist me in the process. This is currently a discussion of possibilities, and I need your help with the technical side. I own a suzuki fiero, 2003 model. She has been beefed up to run a RTR 160 piston, with the respective carb. My mod request is mostly due to the damages incurred, during our trip to Leh-Ladhak on the bike. And I need to upgrade the bike, to full adventure mode, where such damages can be avoided. Let me speciify the damages and then will revert back to the modifications;
Damages:
1. Front suspension bent, springs have been powdered.
2. Swingarm and rear suspension badly hammered.
To be honest, this is the result of my riding and not her fault. She tried her best, but our load capacity and my weight and the terrain, coupled with my riding skills, just tore her down. In view of this, I would like to make the below modification;
1. Front suspension upgrade to that of Suzuki GS150R.
2. Rear suspension upgrade to that of Suzuki GS150R.
3. Swingarm upgrade to RTR 180 with disc brake option.
These are my current problems that I have speculated would occur and wondering how I could counter them;
1. As the front suspension from GS150R is a disc brake model, I need a spoke wheel, with matching disk proportions for the front wheel.
2. Rear spoke wheel with matching proportions to the rear wheel of an RTR 180, with disk brake.
3. Ride height increase.
4. Wheelbase increase.
5. Suspension action and fitting, to fiero.
There are a few logical reasons for the upgrades I have mentioned here. Firstly, I would be adding a travel/adventure carrier to the rear, with aluminium boxes, for long range travel. The Fiero would have to hold the weight of me with pillion and luggage without causing too much damage to suspension, in case of bad roads. The suzuki GS150R is a 150+ kilo bike, and the feiro is 130kgs. The suspension designed for the fiero can take a lot of hammering, no doubt, as I have seen it being used even in dirt races. But dirt races, don't span 20,000km. The added weight would require a better suspension, for the long run, and this mod, would give me a twenty kilo leverage over the previous shocks, on normal suspension setting. The increase in ride height should help, avoid any damages from sharper materials to the rear engine casing, or exhaust, though I feel the centre of gravity of the bike would change and a longer wheel base should help smoothen the ride. Flickability on city roads, would be affected, as well as the suspension would be stiffer. So I need to work on those things. I would like this to be a discussion with anybody who has any idea about motorcycle mechanisms, and I am willing and waiting for your advise and an open debate.
Future mods may include going the fuel injection way, but I am holding of on that for now. I even plan to introduce a tank with higher capacity, but am not sure of the ergonomics of such an act. The centre of gravity or balance, being my main concern.
